Well this is the same argument Microsoft make. "It's useful for us (and you) so it must be turned on". But I don't want my computer looking over my shoulder, anonymised or not. Other FOSS projects have been nice and asking about it (like Debian since forever with their popularity contest). The feeling of privacy is important too, it's not just about whether you can have any negative effects in life. And our privacy has been infringed so much that there is a big countermovement now. It's the industry's own fault. I used to be OK with it but because so many supposedly-innocent telemetry and tracking turned out to be malicious I no longer believe in a distinction between 'good' and 'bad' telemetry. That mindset also solves the problem of having to read every privacy policy before agreeing to stuff and be on the lookout for sneaky changes. Even though I think Mozilla is trustworthy as such, the concept of telemetry is just dead in the water in the pro-privacy community. Which is of couse a major percentage of Mozilla's userbase. A poll in-browser would be a good idea IMO. Just put it in the menu and lots of users will answer it.
